IMPROVEMENT IN SOFA-BED MATTRESSES.

, Specification forming part of Letters Patent No. 150,290, dated April28, 1874; application filed March 20, 1873.

To all whom it may concern:

Be it known that we, CHARLES L. CLOSE, PHILLIP C. SCHOENECK, andFREDERICK J. CLOSE, of Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have invented a new and useful Improvement in SofaBedMattresses; and we do hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawing, forming part of this specification, in which- Figure 1 is aView of the sofa when opened, and illustrates the manner in which it istransformed into a bed. Fig. 2 is. a view of our improved mattress.

Our invention consists of a folding springmattress for bed-lounges, theframe of which is so made that the mattress is free from hard ridges andprojections, or partially cushioned portions.

To enable others skilled in the art to make and use our invention, wewill describe its construction and manner of use.

The cushion k is made on one side of the folding mattress m. Themattress m is a spring-mattress, made on a folding frame, which ishinged at the ends m, and has no projecting piece or side along thejoint between the two halves, or at any other point,

except around theedge m, so that it is entirely free from hard ridges orprojections. This mattress is as perfectly and evenly cushioned at allparts as the ordinary springmattress. It rests in the sofa-frame it,upon the fiat piece h, and opens, as shown in Fig.

2, into the eXtension-frame'w. The frame a is provided with ahead-cushion, n, and side and end pieces a a which extend up around themattress, as shown.

The mattress m is removable, and can be used separately from the sofa.

What we claim as our invention,and desire to secure by Letters Patent,is-- The folding spring-sofa mattress m, upholstered on one of its sidesto form the cushion k, constructed upon a frame which extends around itsouter edge, and is hinged at the ends m, to form a uniformly soft andelastic bed, substantially as described.

In testimony whereof we, the said CHARLES L. CLosE, PHILLIP C.ScHoENEoK, and FRED- ERICK J. CLOSE, have hereunto set our hands.
